At present, only 159 sq. km (78%) is covered by the sewerage system out of present habitable area of 204 sq.kms of Surat. This serves around 92% of the total population. The area of the city limits of surat city, covered under this DPR of novation of sewage treatment plant at Dindoli under Dindoli Drainage Zone is 20.68 Sq.km. The population covered under this DPR for the
